• a triangular inner front wall section having first, second and third inner front wall sides, an inner front wall notch being defined along the third inner front wall side, the third inner front wall side being connected to the third outer front wall side and the triangular inner front wall section being folded to lie adjacent to the triangular outer front wall section therealong;
• first and second inner wall reinforcement sections being connected to the first and second inner front wall sides, respectively, and folded therealong to lie adjacent to the triangular inner front wall section such that the triangular inner front wall section lies between the triangular outer front wall section and the first and second inner wall reinforcement sections;
• a triangular inner rear wall section connected to the first outer front wall side and folded therealong to lie adjacent to the first and second inner wall reinforcement sections such that the first and second inner wall reinforcement sections lie between the triangular inner front wall section and the triangular inner rear wall section;
• a triangular outer rear wall section having first, second and third outer rear wall sides, the first outer rear wall side being connected to the second outer front wall side and folded therealong to lie adjacent to the triangular inner rear wall section such that the triangular inner rear wall section lies between the first and second inner wall reinforcement sections and the triangular outer rear wall section;
• and
• a retention flap connected to the third outer rear wall side and folded therealong to lie between the triangular inner front wall section and the triangular inner rear wall section.
